nates generally a portion of apiece'ot work, having engaged therein a screw threaded bolt, a..portion"tliere0f. being denoted. at 1.0,.and: carriedtby this bolt is a nut II, which is threaded thereon to a point for the fastening of the bolt in place, as best seen in Figure 1, with respect to the said piece of work.

The bolt at diametrically opposite sides thereof is provided with longitudinally disposed channels l2, which arealigned with each other following the axis of the said bolt, and communicate at their outer ends with a bifurcation or slot 13 formed crosswise of the bolt, intersecting its center, and opening through the outer end of the shank of such bolt. The bolt is provided with a transverse passage or bore 14, which is at substantially right angles to the lay of the bifurcation or slot I 3 and is carried through opposite sides of such bolt for free access, the passage or bore l4 being in intersecting relation to the bifurcation or slot I 3.

The nut II in the wall of the clearance for the bolt Ill is provided channel-like key-ways l5 selectively spaced from each other concentrically to the said clearance and open into the latter in its longitudinal direction or aligned with the bolt l0 when engaged in such clearance.

Adapted for cooperation with the bolt and nut is a locking device, comprising a bendable looking wire l6 of a required length, which on application has its end stretch I! resting within one of the channels spect to the laying of the stretch ll of such wire in the channel I2.
